ROOFING'.

Application` led May 26,

To all whom it may concern.

Be it known that I, Mouais H. ELWDGE, a citizen of the United States,residing at New York, inthe county of New York and State of New York, have invented certain new and useful Improvements in Roofing; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates` to what is commercially known as lasphalt shingles or rooting y material, land more particularly to such roofing material which has a Asurface of granu" latedl or crushed slate material; and 1t has for its objects to provide rooting shingles or roofing material ofthe particular kindmentioned which will possess` allthe beneficial effects o f such character of roofing and yety will be free from the objections of lacking in uniformity of color, plain or varigated. In the manufacture of shingles or rooing material of the character mentioned the felting or coating 'lacks uniformi-ty in color and not infrequently presents ,streaks of differ ent shades of the same colorywhich detracts 'from the attractiveness of the roof. The colored slatesmost commonly used are green and red. Each of these slates, crushed or granulated, as av rule are not uniform\ in color. The green slate most often has'in its natural state or formation a dark green and' a` lighter reen or yellow' with no' regularity in the di u sion of the .two colors or shades e of color and when the slate in its crushed orl granulated condition is applied to the asphaltic shingle or roofing these differences in shade or color are, accentuated and as a consequence the surface has a streaky and .Specification of Letters Patent.

.unattractive appearance. These dili'erencas 1n shades or colors are accentuated by reason of' the crushed or granulated slate absorbing to a greater' or less extent the oily constituents of the asphaltum with which the base or felt has been treated and thus the lack of harmony oruniformity in the surface is to that extent accentuated. The same 1s true of the red slate when crushed or granulated and applied to the roofing inaterlal as the slate absorbs oil from the as;- pl'laltum and the differences in the Shadil of red accentuated and-the same unattractive appearance presented. These l conditions also tend to deaden the colors and thus the rooting is lacking the life or warmth which contributes .to its attractiveness.

Ihave found that by mixing the crushed or granulated green slate, g, with' the crushed or granulated red slate, o", and workmg the same into the surface of the as phalted felt base A, these natural imperfections in the tvvo colored slates are so disseminated or diiused that the slate, coating or covering is freed from the streaky unattractive appearance and a surface produced of a substantially uniform variegated color, the green and the red standing out in contrasting relation so that an attractive mottled surface of contrasting intermingled particles is presented, the contrasting intermingled particles tending to relieve the dullness in color which exists when only onecolored slate is used, and the absorption of the oil of the asphaltum bythe crushed or granulated slate is offset or counteracted by the contrasting colors of the mottled surface produced by the intermingling of the two distinctive colors of slate.

In the drawing Figure 1 is a front view of the asphalted felt base of the roofing;

Fig. 2 a front View of the improved roofing;`

and Fig. 3 a face view of theroofng, on an enlarged scale for clearness of illustration.

In the manner hereinbefore described, I am enabled to produce a very attractive, effective, and artistic appearance to the roofing and at the same time have the roofing material possess advantages found to exist in-fan-asphaltic felt base provided with a protecting coat of crushed or granulated slate. Various shades of a mottled crushed or granulated slate surface may be produced by mixing or intermingling a greater quantity of the darker material with the lighter, both as to the green and the red alo `colored slate, so that if a darker shade or color is desired a greater quantity* of the darker material Will be mixed Wlth the lighter colored material, and on the other hand if a lighter colored roof. is desired, a

greater percentage of the lighter colored slate will be mixed lwith a smaller quantity l of darker colored slate, and thus there may be produced a lighter or a darker colored surface as desired. In either case there is produced a mottled surface of a substantially uniform color made up of intermingled contrasting colors of crushed or' v granulated slatefree from the serlously obother colored slates than the tvvo mentioned may be used in forming the coat or covering and be Within the scope of the invention. The shingles or roll roong of the type mentioned, that is an asphaltic felt with a coating of crushed slate, is formed in the ordinary Way but the contrasting colored crushed slate coat is formed in the manner I have described and 'for the purposes stated.

Having described my invention and set forth its merits, what I claim is:

l. The Within described slate roofing comprising a base and a coating formed of a uniform mixture of crushed or granulated slates of distinctively different colors interrningled to produce a slate surface of contrasting intermingled colors of substantially uniform character throughout the coating.

2. T he Within described slate roofing comprising an asphalted felt base and a surface Coat formed of a uniform mixture of crushed or granulated slates of distinctively different colors intermingled to produce a contrasting eifect of intermingled colors of substantially uniform character throughout the coating.

In testimony whereof I aix my signature in presence of two Witnesses.
